Some 2021-2022 F-150 vehicles may exhibit a condition where a front and/or crew cab rear door will not open from the exterior handle when the doors are unlocked or where the exterior handle seems blocked from reaching full travel (full stroke). This may be due to the engagement of the resettable inertia lock feature within the handle reinforcement mechanism. If this is the case, the mechanism can be reset to allow full handle function. To correct the condition, follow the Service Procedure to reset the inertia lock.
